The filaments 3 are conveyed from b and 21c and supplied to the winding lead gripping nipper 10. The wire 3 has a predetermined length, that is, a wire length required for winding a plurality of turns around the annular body 1, for example, at intervals of 10 m, by a cutter (not shown) provided near the winding lead gripping nipper 10. It is cut and the tip of the filament 3 is treated in the following manner. <Treatment of Tip of Wire 3> FIG. 25 shows treatment of the tip of wire 3. The three filaments 3 are cut at a predetermined filament length (for example, 10 m) by a cutter (not shown) provided near the winding lead gripping nipper 10, and the three filaments 3 are cut. The distal end portion 61 of the filament 3 is twisted by gripping the distal end of the wire with a human hand or a rotating machine and rotating it several times.

A protective tube 62 is covered so as to cover the tip portion 61 of the filament 3. This protective tube 62
Is heat-shrinkable and closely adheres to the tip portion 61 of the filament 3.
The three lines 3 are prevented from being scattered, and the sharpness of the cutting edge 63 at the tip portion 61 of the lines 3 is protected.
The treatment of the tip of the filament 3 is particularly effective when the inner diameter of the hole 1a of the annular body 1 is small. <Structure of Chuck Device 4> Next, the chuck device 4 will be described with reference to FIG.

The chuck device 4 is slidably provided on a guide rail G extending from one side of the annular body 1 gripped by the gripping device 2 to the other side. The chuck device 4 includes a first chuck 3 that holds the tip of the filament 3.
3 and a second chuck 34 for gripping a portion of the filament 3 slightly separated from the gripped portion by the first chuck 33.

Then, the first chuck 33 and the second chuck 34 are respectively movable forward and backward toward the filament 3 to advance and retract the frame 3.
5, a pair of chuck claws 36 that can be opened and closed are provided. The advancing and retracting of the advancing and retracting frame 35 and the opening and closing of the chuck claw 36 are performed by an air cylinder device (not shown).

Then, the first chuck 33 and the second chuck 34 grip the filament 3 while advancing toward the filament 3, and the hole 1a from one side of the annular body 1 to the other side.
When passing the wire 3 through the first chuck 33, the first chuck 33 first releases the wire 3 and then retracts to avoid the grip plate 11 that constitutes the grip device 2.

Thereafter, the filament 3 is inserted and guided into the hole 1a only by the second chuck 34, and when the filament 3 passes through the hole 1a,
The first chuck 33 advances and grips the tip of the filament 3, and at about the same time, the second chuck 34 releases the filament 3 and retreats.
Therefore, when the second chuck 34 subsequently slides to the other side of the annular body 1, the second chuck 34 can avoid the gripping device 2.

After the second chuck 34 has come to the other side of the annular body 1, the second chuck 34 may re-advance like the first chuck 33 to grasp the filament 3, but in this embodiment, it is possible. Since the first chuck 33 has grasped the distal end portion of the filament 3 first, the second chuck 34 is left in the retracted state at this point, and the filament 3 is retained only by the first chuck 33.
To convey and guide. However, it is not limited to the case where the filament 3 is conveyed only by the first chuck 33, and both the first chuck 33 and the second chuck 34, or the second chuck 34.
You may make it guide | induce the filament 3 by grasping the filament 3 only.

The chuck device 4 is formed so as to rotate around the first fulcrum 5 and the second fulcrum 180 by 180 degrees, and to wind the filament 3 half-turn around them. That is, the first chuck 33 and the second chuck 34 rotate around the first fulcrum 5 and the second fulcrum 6, and the line 3 being grasped is fixed to the first fulcrum 5 by the first fulcrum 5.
Alternatively, it is wrapped around the second fulcrum 6.

In order to perform accurate winding without being affected by the number of windings of the process filament 3, the elongation of the wire, and the overlapping of the wires,
In consideration of the first fulcrum 5, the second fulcrum 6 and the position data of the chuck device 4, the filament 3 is cut into a predetermined length. <Automatic Winding Method> Next, an automatic winding method of the wire 3 on the annular body 1 using the apparatus described above will be described. First, the annular body 1 is held between the annular body outer peripheral surface grip plates 11a and 11b.

Next, (a) with the annular body 1 as a reference, the filament 3 is passed through the hole 1a of the annular body 1 and the tip of the filament 3 is inserted into the first chuck 33 and / or the second chuck 34 of the chuck device 4.
The chuck device 4 is gripped by the grip and extends toward one side, and the circumference of the first fulcrum 5 arranged on one side of the annular body 1 is made a U-turn by a half rotation of the chuck device 4, and the chuck device 4 slides on the guide rail G. The wire 3 is guided to the other side of the annular body 1 by a motion, and the circumference of the second fulcrum 6 arranged on the other side of the annular body 1 is made a U-turn by a half rotation of the chuck device 4 and is positioned immediately thereafter. , Secure the length required for winding and fix the base end of the filament 3 for initial setting. In this example, the initial setting was performed by the following procedure (FIGS. 1 and 2).

(A-1) The tip of the wire 3 is passed from the winding lead gripping nipper 10 between the ring-shaped body 1 and the ring-shaped body left side gripping plate 11a, and from the other side of the ring-shaped body 1 to the ring-shaped body 1. And is guided to one side of the annular body 1. afterwards,
The first chuck 33 and the second chuck 34 half-turn, and the filament 3 makes a U-turn around the first fulcrum 5.

(A-2) After that, the chucking device 4 moves to the left, gets over the annular body 1 from one side to the other side, and the tip of the filament 3 is passed to the other side of the annular body 1. To make a U-turn around the second fulcrum 6 arranged on the other side of the annular body 1. Then, the movement is stopped when the length of the filament 3 reaches a predetermined length, and the stop position is set as the initial position.

(A-3) The filament 3 is measured at the tip of the filament 3 and cut at a point of a prescribed filament length, and the initial setting is made. At the stage of initial setting, as shown in FIG. 1, the tip of the filament 3 is held by the first chuck 33 and the second chuck 34 of the chuck device 4. However, only the first chuck 33 or the second chuck 33
It may be gripped only by the chuck 34. (b) Next, the arm 7b is rotated clockwise around the large-diameter rotary shaft 7a by the driving force of the drive transmission mechanism (not shown), so that the first fulcrum 5 is circular to one side from the initial position P0. It rotates away from the body 1 and stops moving at a certain position P1 on the circumference (FIGS. 3 and 4). That is, the line 3 is at the position P
By moving to 1, the filaments 3 are tensioned with a certain tension. (c) Next, since the arm body 8b rotates counterclockwise around the large-diameter rotary shaft 8a by the driving force of the drive transmission mechanism,
The fulcrum 6 rotates from the initial position P2 to the other side away from the annular body 1 and stops moving at a certain position P3 on the circumference (FIGS. 5 and 6).

That is, the filament 3 projects to the other side, and the first fulcrum 5 is pulled to the other side. Then,
Since the first fulcrum 5 rotates in the counterclockwise direction around the small-diameter rotation shaft 7c, the filament 3 deviates from the first fulcrum 5. First
When the fulcrum 5 of is deviated from the filament 3, the filament 3 is wound around the annular body 1 by a tension.

(D) Next, from the other side of the annular body 1 to the one side through the tip of the filament 3 through the hole 1a,
Make a U-turn around the fulcrum 5 of. This operation will be described in detail below.

(D-1) First, the chuck device 4 moves to the right toward the annular body 1, and stops at a position where the tip of the chuck device 4 approaches the annular body left side holding plate 11a, and Three
The leading end of is guided to the hole 1a of the annular body 1 (FIGS. 7 and 8).

(D-2) Next, the first chuck 33, which has gripped the filament 3, releases the filament 3 and retreats, and the chuck device 4 advances beyond the side surface gripping plates 11a, 11b of the annular body. Then, the filament 3 gripped by the second chuck 34 is guided to the hole 1a. Then, the chuck device 4 moves the annular body side gripping plate 11
After stopping at a position sandwiching a and 11b, the first chuck 33 again descends and grips the tip of the filament 3 (Figs. 9 and 10).

(D-3) Second chuck 34 of chuck device 4
Retreats after releasing the wire 3, and the entire chuck device 4 moves to the right to stop the second chuck 34 at a position close to the right side gripping plate 11b of the annular body. Then, at that position, the second chuck 34 again descends to grip the filament 3 (FIGS. 11 and 12).

(D-4) The entire chuck device 4 is further moved to the right, and the first chuck 33 and the second chuck 34 stop at the position sandwiching the first fulcrum (FIGS. 13 and 14). (d-5) Next, at this position, the first chuck 33 and the second chuck 34 of the chuck device 4 make a half rotation around the first fulcrum 5, so that the filament 3 moves around the first fulcrum 5. Make a U-turn. (FIGS. 15 and 16).

(E) Next, by the driving force of the drive transmission mechanism,
Since the arm body 7b rotates clockwise around the large-diameter rotary shaft 7a, the first fulcrum 5 rotates away from the annular body 1 to one side from the initial position P0, and a certain position on the circumference. The movement is stopped at P1.

That is, the filament 3 projects to one side, and the second fulcrum 6 is pulled to one side. Then,
The second fulcrum 6 rotates in the clockwise direction around the small-diameter rotary shaft 8c, so that the filament 3 deviates from the second fulcrum 6. Second
When the fulcrum 6 of is disengaged from the filament 3, the filament 3 is wound around the annular body 1 by a tension (FIGS. 17 and 18).

(F) Furthermore, the first chuck 33 and the second chuck 34 grasp the tip of the filament 3 and guide it from one side of the annular body 1 to the other side, and the first chuck 33 and the second chuck 34 And stop at a position sandwiching the second fulcrum 6 (Fig. 1
9, FIG. 20).

Then, the first chuck 3 of the chuck device 4
The third and second chucks 34 make a half turn to make a U-turn around the second fulcrum 6 and stop at a position sandwiching the second fulcrum 6 with the first chuck 33 and the second chuck 34 (FIG. 21,
FIG. 22). That is, the state returns to the state of the step (c).

(G) Thereafter, the annular body 1 is rotated by a predetermined pitch and the steps (c) to (f) are repeated to wind the filament 3 around the annular body 1 for a plurality of turns. As described above, according to the method and apparatus of the present embodiment, it is easy to adapt to automation, and it is possible to mechanically wind the filament by using the apparatus and apparatus. In addition, winding a line around the first and second fulcrums,
By using the first rotating device 7 and the second rotating device 8 to rotate and move the first fulcrum 5 and the second fulcrum 6 alternately away from the annular body 1, Since the filament 3 is wound around the annular body 1 without removing the fulcrum, the filament can be reliably wound around the annular body, and the first fulcrum or the second fulcrum 6 is largely moved linearly. There is no need. Further, by providing the first and second fulcrums, the movement of the chuck device and the rotational movement of the fulcrum can be shared at the same time, so that the stroke of the reciprocating motion of the chuck device is shortened and the moving work of the chuck device is accelerated. Therefore, the space for the device is small and the structure of the device is simple.

Since the unwound filament 3 becomes shorter as the filament 3 is wound, the first fulcrum 5 and the second fulcrum 6 are formed as the winding is repeated. It is necessary to reduce the distance. Therefore, the positions of the first fulcrum 5 and the second fulcrum 6 arranged on both sides of the annular body 1 are adjusted according to the line length.

By the above operation, when the filament 3 is wound around the annular body 1 a required number of times, the winding start and the end of the filament 3 are cut to complete the annular body in which the filament is wound. .

[0046]

According to the method and apparatus of the present invention, the wire can be automatically wound around the annular body, and the wire can be wound around the first and second fulcrums, and the first rotating device can be used. And the second rotation device are used to rotate and move the first fulcrum and the second fulcrum alternately so as to separate from the annular body, thereby removing the one fulcrum from the linear body and moving the linear body to the annular body. Since it is wound around, it is not necessary to move the first fulcrum or the second fulcrum largely in a straight line. Further, by providing the first and second fulcrums, the movement of the chuck device and the rotational movement of the fulcrum can be shared at the same time, so that the stroke of the reciprocating motion of the chuck device is shortened,
The work of moving the chuck device becomes faster. Therefore, the space for the device is small and the structure of the device is simple.
